چکیده
The combined effects of deviation from ideal in integrator upon the characteristics of the integrators. Inverting and noninverting magnitude and phase on the performance of integrator-based active filters integrators for use in active filters which are independent of first-order and is investigated. The limitations of using the integrator Q-factor as a second-order operational amplifier time constant effects and require no measure of integrator performance are discussed. Conditions for minimizamplifier matching are introduced. These new integrators are compared ing the operational amplifier gain bandwidth product effects on with existing actively compensated configurations directly and in a filter integrator-based active filters are established which are dependent only structure. Experimental results are presented which confirm the theoretical development. Manuscript received February 9, 198 1; revised April 22, 1982.

A practical method of designing active filters in which the transfer function is independent of both firstand second-order operational amplifier time constant effects is presented. Neither matched operational amplifiers nor a tuning procedure dependent on an active parameter is required. The active portion of these filters is universal and readily integrable since it is comprised of conventiona...
متن کاملParasitic Pole Approximation Techn iques for Active F ilte r Design
I T IS A well-known fact that the frequency response of an operational amplifier (op amp) affects the performance of active filters employing these devices. The frequency dependent gain of the op amp causes both a perturbation in the desired poles of the active filter from their nominal position and the introduction of parasitic poles in the active transfer function. It has also been observed b...
